This is the 30-liter version of Mammut's popular Seon Courier model. Currently, they only sell up to the 20-liter size, so this type is considered rare. It can be used in various situations, such as for everyday use and mountain climbing. It has been used infrequently, so the condition is good. It has excellent water repellency, and the storage compartment for PCs and documents on the back uses water-resistant zippers. Thank you for your consideration.
